Transparency component for the colours

[csaez]

I just got this in my mailbox and thought the best place for it would be here. It sounds like a good opt-in feature, although it brings a few tricky ones to the table (i.e. alpha sorting).

Thanks for the suggestion, Zeno!

Hi! Just wanted to say a quick thanks for open sourcing your mscreen library! Keep up the good work.

Also, it would be incredibly cool if a transparency component for the colours was implemented (using gl_blend?)

Thanks!
